Abstract : The third-order elastic coefficients of crystals are defined in different manners in the literature resulting in different numerical values for the same coefficients. The derivations of three definitions of the third-order elastic stiffnesses are considered in the first section of this report while simplifications for the third-order stiffnesses for the various crystal classes are given in the second section.
